Methods For Using Quantum Computers - Quantinuum Ltd
Summary
Quantinuum Ltd filed US patent application US20260111775A1, published April 23, 2026, covering methods for enhancing quantum state preparation circuits to encode multivariate probability distributions for quantum Monte Carlo integration. The application, filed July 26, 2023 (application no. 18998150), names Steven Herbert and Michael Spranger as inventors and carries CPC classifications G06N 10/20, G06N 10/40, and G06N 10/60. The invention adds dimensions for sums, products, maxima/minima and includes a flag qubit for conditional control in QMCI computations.
“There is provided a series of steps, according to user-defined instructions, that enhance a quantum state preparation circuit encoding some multivariate probability distribution such that the circuit further includes dimensions pertaining to sums, products and maxima/minima of other dimensions, and optionally includes a further "flag" qubit that will act as a conditional control in quantum Monte Carlo integration (QMCI).”
About this source
USPTO classification G06N covers computer systems based on specific computational models: neural networks, knowledge representation, fuzzy logic, expert systems, evolutionary algorithms. With the AI patent boom, this is one of the most-filed application classes in the office. Every newly published application in G06N lands in this feed, around 230 a month. Patent applications publish 18 months after filing, so this feed reveals what AI labs and companies were working on in the prior year and a half. Watch this if you compete in machine learning, file freedom-to-operate analyses, scout acquisition targets in AI infrastructure, or track which research groups are converting publications to patents. GovPing pulls each application with the filing number, title, applicant, and abstract.
What changed
The USPTO published patent application US20260111775A1 for Quantinuum Ltd, covering methods for enhancing quantum state preparation circuits. The circuits encode multivariate probability distributions and include additional dimensions for sums, products, and maxima/minima operations, with an optional flag qubit enabling conditional control in quantum Monte Carlo integration (QMCI) computations.
Competitors developing quantum computing applications in science and engineering should monitor Quantinuum Ltd's IP portfolio in this area. The patent's broad claim to QMCI enhancement methods may affect freedom-to-operate considerations for firms working on quantum simulation, computational chemistry, or financial modelling using quantum Monte Carlo techniques.

Abstract
There is provided a series of steps, according to user-defined instructions, that enhance a quantum state preparation circuit encoding some multivariate probability distribution such that the circuit further includes dimensions pertaining to sums, products and maxima/minima of other dimensions, and optionally includes a further “flag” qubit that will act as a conditional control in quantum Monte Carlo integration (QMCI). The series of steps are useful for computations in many applications in science and engineering.
